Measuring Savings: A Postretrofit Analysis of 436 Chicago Bungalows

Since 2006, the Historic Chicago Bungalow Association (HCBA) has provided more than 2,500 energy efficiency grants to low- and moderate-income bungalow owners throughout the city of Chicago. The HCBA EnergySavers program supports the organization’s mission to help bring resources to members in an effort to help preserve, maintain, and improve comfort in these aging homes. However, after several years of utilizing modeled/presumed savings from the insulation and air sealing measures provided by the grant program, HCBA reached out to Elevate Energy for an energy use analysis to measure homeowners’ actual post-retrofit savings.
